Surface Finishing

Processes – Surface Finishing

Manufacture is carried out using the latest glass processing plant and equipment at our factory in Perth. With our highly skilled and experienced operators we can also offer customised samples and short run production.

Surface Grinding

Surface grinding removes stock from the glass to flatten and reduce in thickness in preparation for lapping.

Lapping

Many glass products are created from raw material i.e. blanks or slabs. After glass has been reduced in thickness it then requires fine grinding (lapping) to achieve the tight tolerances often specified by customers.

Polishing

Similar to lapping and sequentially follows the lapping process. The glass product is surface-polished using high quality cerium oxide on a felt bed.

Coating

Glass can be thin film coated to produce a wide range of effects for use in various industrial and commercial applications i.e. anti-reflective, ITO, and dichroic.

Sandblasting

We have a CNC machine available to decorate a wide range of glass products i.e. diffusers for lighting, patterned household or display shelves etc.

Our machine can handle glass up to 2800mm x 1100mm in size. Glass is held vertically using vacuum suction cups. Magnets are located behind a rubber matting to allow steel plates to be fixed onto the glass. This provides a firm positional base for sandblasted patterns and images to be created.

Clear Shield

This is a coating we apply to glass which makes the glass non-stick and self-cleaning. When glass is coated in this way, any water will simply run off and carry with it any dust or dirt.

This coating process is ideal for glass which is difficult to access and therefore clean by conventional means. Clear Shield coating is also highly desirable on sandblasted products as it effectively prevents finger print marking while handling the glass.

Screen Printing

We have a variety of silk screening equipment for decorating glass products. With this equipment we can also print identification and standard markings onto the glass.
